Application filed May 13. 18 5. (No model.)

To all whom it may concern;

Be it known that l, JOHN TESSEYMAN, 0t

Dayton, in the county of Montgomery and State of Ohio, have invented nand useful I Improvements in CHY-AXlG'BOX Covers; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, which form apart of this specification.

This invention relates to certain new and novel improvements in the c)nst ruction of caraxle-box covers.

The invention consists in the peculiar means employed for retaining thecover upon the box against accidental displacement, whether in its openor closed positions, and in the peculiar construction, arrangement, andcombinations of the various parts, all as more fully hereinafter setforth.

Figure l is a perspective view showing the cover opened and partlybroken away to show the formation of the guiding-grooves in the edges ofthe cover. Fig. 2 is a side view with the cover closed and partly brokenaway to show the engagement of the parts. Fig. 3 a detached perspectiveof the rear side of the cover. Fig. 4 is a vertical central section withthe cover open.

In the accompanying drawings, wnich form a part of this speei tieation,A represents a caraxle box, and ll the door-opening through which thewaste and lubricant are intro duced. At the lower corners of thedooropening and upon-the sides of the box are cast the curvedwedge-blocks O, the. outer or straight edges of which are lush with theedges of the door-opening. At the upper corners are cast theoutwardlyprojecting lugs D, being a continuation of the head a at thetop of the box. The lugs are rounded upon their tops, while they aretlat upon their under sides.

E is the cover, provided upon its two side edges with theinwardly-projecting L- shaped flanges F, and upon the top edge with thecurved flange G, uniting at the corners with the flanges F, thus forminga continuous flange upon the two sides and top of the cover, as shown.The flanges F are, near their upper ends, formed upon a curvedenlargement from b to 0, while from b, which is the point nearest to theinner face of the cover; such flanges F gradually diverge from the lineof the cover to their open ends. Upon the inner face of the cover, andat a point slightly above its center and almost or about in line withthe L center of the curved enlargement of the side flanges, F, is castan inwardly-projecting elon gated stop. H.

In practice the cover is placed upon the box in such manner that thelugs D will enter the open ends of the flange F. It is then drawnforward until the stop H strikes against the head a upon the upper edgeof the box and the lugs D have passed into the enlargement of the sideflanges. the position of the cover now being in nearly a horizoutalplane. The cover can now be turned upon the lugs D, closely over thedooropening, and, being allowed to drop, the curved wedge-blocks Owillenter the side flanges, and by their engageinent therewith, and theengagement of the lugs D with the upper portion of said flanges, drawthe cover tightly against the edges oi the box: around the door-opening.

What I claim as my invent-ion is 1. A cover for car-axle boxes providedupon its two side edges with inward]y-projecting flanges, and upon thetop edge with a curved flange, uniting at the corners with the sideflanges, each oi said side flanges formed with a curved enlargement nearits upper end, and diverging at the point b from the line of the coverto its open end, substantially as and for the purpose specified.

In a car-axle box, the combination of the following elements; anaxle-box, A, provided at the lower corners of the door-opening with theoutwardly-proj ecti n g wedge-blocks G, and at the top with a head, a,terminating ateach end in the lugs D, rounded on top and flattened onthe bottom, a cover, D, provided with theinwardlyprojecting Lshapedflanges F upon its two edges formed upon a curved enlargement near theirupper ends, and a curved flange, G, upon the upper edge, whenconstructed, combined and operating substantially in the manner and forthe purposes described.
